SELF-MEASURING RECEPTACLE.

SPECIFICATION forming part of Letters Patent No. 598,503, dated February 8, 1898.

Application filed March 11, 1897.

To all whom it may concern:

Be it known that I, WILLIAM FORREST, of Cortland, in the county of Cortland, in the State of New York, have invented new and useful Improvements in Self-Measuring Receptacles, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in self-measurin g receptacles, and has for its object the production of a simple and effective device particularly applicable for use by grocery-keepers and other small retailers of oil for automatically measuring the amount of oil within the receptacle; and to this end the invention consists, essentially, in the general combination, construction, and arrangement of the component parts of a self-measuring receptacle, all as hereinafter fully described, and pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figure 1 is an elevation of my improved self-measuring receptacle, the ,rod or stem secured to the float being shown as partly raised. Fig. 2 is a transverse section taken on line 2 2, Fig. 1; and Fig. 3is a vertical section taken on line 3 3, Fig. 2.

A represents my improved self-measuring receptacle,which is preferably provided with a substantially upright tube B, depending from its top walla, and a float C, movable within the tube B. The top wall a, is usually formed with a depressed central portion a, which is provided with an aperture a and an upwardly-projecting threaded flange a surrounding said aperture. The bottom wall a of the receptacle A is provided with an up wardly-projecting ring or annular flange 0L5, arranged in alinement with the aperture a and formed with a suitable inlet-opening a Figs. 2 and 3. The receptacle A is also provided with suitable means for admitting and Withdrawing the oil, but as said means forms no part of my present invention 1 have deemed it unnecessary to herein illustrate and describe the same.

Serial No. 626,982. (No model.)

arranged within the ring or annular flange a The float C closely fits the tube B and is provided with an upwardly-projecting rod or stem 0, movable through the aperture a The rod or stem 0 is provided with suitable graduations c',which are displayed above the top edge of the flange 01, as the float C rises and indicate the number of gallons or other quantities of oil within the receptacle A. A suitable threaded cap 0 is removably mounted upon the upper end of the rod or stem 0 and maybe detachably engaged with the threaded flange a for holding the float in its depressed position.

In the operation of my invention the grocery-keeper or other retailer fills the oil within the receptacle A, and since the oil stands at a uniform level within the tubeB and the receptacle A the float C is correspondingly raised as the oil is admitted within the receptacle A, and the graduations 0 upon the stem 0, rising from the float C, readily indicate to the grocery-keeper or other retailer the amount of oil admitted within said receptacle. Considerable time is therefore saved in filling my improved self-measuring receptacles, as they may be filled directly from a larger reservoir or barrel without necessitating the use of an additional measuring-receptacle. Moreover, the user of the oil from my improved self-measuring receptacle is informed of the exact amount of oil within the same when first received from the retailer and also during the Withdrawal of the oil as the same is required for use. The construe Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1. The combination of a receptacle formed with an aperture in its top wall, and an upwardly-projecting threaded flange surrounding the aperture, a float movable Within the receptacle and provided with a rod or stem projecting through the aperture, and a threaded cap for surrounding the upper end of the rod or stem and removably engaging the threaded flange and thereby holding the float in its depressed position, substantially as and for the purpose set forth.

2. The combination of a receptacle provided with a normally-closed upper end having its top wall formed with a depressed central portion provided with an aperture and an upwardly-projecting flange surrounding the aperture, a tube depending from the depressed portion of the top wall in alinement with the aperture therein, a float movable within the tube and provided. with a rod or stem projecting through said aperture and having graduations thereon for indicating the quantity of liquid within the receptacle, and a cap for surrounding the upper end of the rod or stem and removably engaging the flange and thereby holding the float in its depressed position, substantially as and for the of the receptacle, the upper end of the tube being secured to the top Wall and having a portion of its upright wall extending laterally beyond the depressed portion of the top wall, for forming an opening in the top of the tube, and a float movable within the tube and provided with a graduated rod or stem projecting through said aperture in the top wall, substantially as and for the purpose set forth.

In testimony whereof I have hereunto signed my name, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 4th day of March, 1897.

WILLIAM FORREST.
